 Never use a person as a substitute for a table extension
or as additional support for a workpiece that is longer or
wider than the basic saw table.
 When cutting irregularly shaped workpieces, plan your
work so it will not pinch the blade. For example, a piece
of molding must lay flat on the saw table. Workpieces
must not twist, rock, or slip while being cut.
When backing up the workpiece, the blade may bind in the
kerf (cut). This is usually caused by sawdust clogging the kerf
or when the blade comes out of the guides. If this happens:
 Place the switch in the OFF position. Wait until the saw
has come to a full and complete stop, then remove the
switch key from the switch assembly. Store key in a safe
place.
 Unplug the saw from the power source.
 Wedge the kerf open with a flat screwdriver or wooden
wedge.
 Open front cover and turn the upper wheel by hand while
backing up the workpiece.
RELIEF CUTS
Relief cuts are made when an intricate curve (too small
a radius for the blade) is to be cut. Cut through a scrap
section of the workpiece to curve in pattern line then carefully
back the blade out. Several relief cuts should be made for
intricate curves before following the pattern line as sections
are cut off of curve "relieving" blade pressure.
SCROLL CUTTING
For general type scroll cutting, follow the pattern lines by
pushing and turning the workpiece at the same time. Do not
try to turn the workpiece while engaged in the blade without
pushing it – the workpiece could bind or twist the blade.
REMOVING JAMMED MATERIAL
Never remove jammed cutoff pieces until the blade has come
to a full and complete stop.
 Place the switch in the OFF position. Wait until the saw
has come to a full and complete stop, then remove the
switch key from the switch assembly. Store key in a safe
place.
 Unplug the saw from the power source before removing
jammed material.
OPERATION
AVOIDING INJURY
 Make sure saw is level and does not rock. Saw should
always be on a firm, level surface with plenty of room for
handling and properly supporting the workpiece.
 Bolt saw to the support surface to prevent slipping,
walking, or sliding during operations like cutting long,
heavy boards.
 Turn saw OFF, remove switch key, and unplug cord from
the power source before moving the saw.
 Do not remove jammed cutoff pieces until blade has come
to a full and complete stop.
 Choose the right size and style blade for the material and
type of cut you plan to do.
 Make sure that the blade teeth point down toward the saw
table, that the blade guides, thrust bearings, and blade
tension are properly adjusted, that the blade guide knob
is tight, and that no parts have excessive play.
 To avoid accidental blade contact, minimize blade
breakage, and provide maximum blade support, always
adjust the blade guide assembly to just clear the
workpiece.
 Use only recommended accessories.
 With the exception of the workpiece and related support
devises, clear everything off the saw table before turning
the saw on.
 Properly support round materials such as dowel rods or
tubing because they have a tendency to roll during a cut
causing the blade to "bite". To avoid this, always use a
"V" block or clamp workpiece to a miter gauge.
 Before removing loose pieces from the saw table, turn
saw off and wait for all moving parts to stop.
LOCKING THE SWITCH
See Figure 12, page 20.
 Place the switch in the OFF position. Wait until the saw
has come to a full and complete stop, then remove the
switch key from the switch assembly. Store key in a safe
place.
BEFORE LEAVING THE SAW
See Figure 12, page 20.
 Place the switch in the OFF position. Wait until the saw
has come to a full and complete stop, then remove the
switch key from the switch assembly. Store key in a safe
place.
 Unplug the saw from the power source.
 Make workshop childproof.
 Release the tension from the saw blade using the RAPID
SET blade tension lever to prolong the life of the blade.
 Lock the shop.
